Abstract
1) The serum Ch-E values in healthy children were indicated as follows: they were in the lowest level in new-horns, rose in sucklings, then gradually fell off and in primary-school age reached a level approximately equal to that in adults.
2) The values were found higher in suckings in the earlier half (up to 6 month of age) than in those in the later half (between 7 and 12 months). In particular, the babies aged one month showed the highest values.
3) No difference by sex could he observed in serum Ch-E values.
